Protection of ovarian function by two distinct methods of ovarian shielding for young female patients who receive total body irradiation.

To prevent ovarian dysfunction due to total body irradiation, we started ovarian shielding at our center (Saitama Medical Center, Jichi Medical University (SMC-JMU)) with a long source axis distance, which is different from the original method used at the University of Tokyo Hospital (UTH). We retrospectively analyzed the outcome of eight patients with a median age of 20.5 years from SMC-JMU and compared the results with the published data for eight patients with a median age of 22 years from UTH.

SIADH is only an atypical clinical feature in a patient with prolactinoma.

A 50-year-old man was admitted to determine the pathogenesis of hyponatremia. He had a poor appetite and was easily fatigued. Physical findings showed that he was conscious and alert.

SIADH closely associated with non-functioning pituitary adenoma.

We demonstrated severe hyponatremia in a 68 year-old man who had pituitary tumor. He had poor appetite and was disoriented. Tests revealed hyponatremia of 110 mmol/l, and he was admitted to Jichi Medical School Omiya Medical Center to undergo further tests.
